I Application filed July 1, 1908.

Patented Dela, 4, 1910. Serial No. 441,3?6. Y

To all whom "it may concern:-

Be it known that LJQSEPH FAWnLL, reside ing at Pittsburg, in the countyof lilleghen y" and State of Pennsylvania, a citizen of the United,Stetes, have invented, or (liseo' gerecl certain new and usefulImprovements in Manipulators for Rolling-Mills, of which improvementsthe following is a specification.

vI11 a patentNo. 915,669, granted March 16, 1909, is shown and(leseri-bei e construction of manipulator mechanism for feed tables ofrolling mills characterized by a combination wherein the mechanism forop erating the turning bars movable back and forth with the header-abutnenl, Wl16fby the ingots are to be shifted latez'ellyon the feed table.

The invention described herein has for its object -21 construct-ion inwliieli the prime mover or motor has a mechanically sliding connectionwith tile till-nine bars, time per mitting such motor to be nxerllyarranged and avoiding the use of extensible conneclzions between 'lliemotor and the sourees of power supply The invention is l'iereinaltermore fully described and chimed. v

and 9 are elevations showing pposif of the combined ingot turning andmechanism and Fig. 10 is a View eerily in section and partly inelevation of the binecl ingot shifter and turning: lam.

In the practice of my invention the feed table is constructed as regardsl'lie feed rollersr 1 and their operating mechanism, in the usual or anysuitable manner. Heads or zilnitinents 2 are supporteci above the planeby iurni'.

antler one elf ilie lying is :1 plan latter by guielesl, preferablytubularancl having bearings in blocks 6 arranged above and in line withthe side franies of the feed table. It is preferred that these blocks-Gshoulei hejormed integral wit i the caps for the'bearings of thejournals of the feed rollere 1. or as many thereof eeilere spanned bythe head or abutment as described in the application referred to" Thesegxzirie members of the feed rollers "and at rightangles toihe Vabutinenls by bearings above the plenesof the rollers there will. beliability of tie glllihES' or choir bearings bei'ogent by scale, Theseheads or evoutmenee ere transversely of ul e by any I suitablemechanism, pr ferebly by means. of cylinoiers 153 having eornnion rainor piston ll connected which is secured to slime 1.3. v Ari 9 areeenneeieal lo LfilS shaft l elieir upper eiu'ls Ex linl-ts m Elie headsor eluemente v v -23 Will n. are preferably constructed Willislioololers to enon. hould to'verl. refer} the feecl rollers. il lieeeearning so supgoreeel as '30 be capable e merit trene'verseiv Lhe iableably to move their movement irer To end is turning burs grooves formalint-ieai feces of the or lner or members 19 preferably neene 0 links 18connecier. at oneenrl/lo the upper encis'of the lTilfll'llBg and havingtheir opposiie enls loosely cor eeiecl to she l, 1! carried by iihelifting .llie l Ling the outer ends of arms secured to shafts 23 mountedin siiiieble bearings carried by have their outer ends connected to theram 25 of the fluid pressure cylinder 26. As will. be readily understoodthe movement of this ""ram will cause a vertical movement of the .ferredthat the turning beams 19, pivotally supported on the outer en the guideposts the outer ends of the lifting members and a corresponding movement of the turning bars. In order to guide fiv the lifting members andintegral with the guides 4, said postsex tending up through sleeves 29secured to the lifting members as clearly shown in Figs. 1, 2 and 4. v

In lieu of moving the lifting members equally throughout their entirelength as in the construction shown in Figs. 1 to l, such liftingmembers may have their outer ends pivotally connected to standards 30secured to the rear ends of'the tubular guides 4:. In this constructionthe inner ends of the lifting members rest upon shoes 31 earned by thearm 22 secured to the shaft 23*,wh1ch has an arm 24 also securedtheretoand having its end connected to the ram 25 of the cy ind er 26.

It is characteristic of the construction shownherein that the liftingmembers carrying the turning bars are slidably supported by themechanism em'loyed for raising and lowering these members and theturning bars. As hereinbefore stated it is prebars should movetransversely of the feed table with the heads or abutments and asynchronous movement of the turning bars with their lifting memberswithtl'ie heads or'abutments is assure in the construction shown inFigs. '1 to 4 by 27 and inthe construction 6 by the connectiouof Figs. 5and lifting members wlth shown in the guides 4E.

As shown in Fi s. 7 to 10, the lateral shifting and the axlal'turning ofthe ingot may be effected by the same part or mem- A desirableconstruction for this purhead or abutment 2* provided with a series ofbars or fingers 15 suitably spaced to extend down between the feedrollers 1 and provided with ingot engaging shoulders 16. The head orabutment 2 ,is secured to shifting and lifting which are mounted insleevgs 20;

arms 22 secure on shafts 23 mounted in stationary bearings 50 on theframe of the manipulator. 1 The shaft is oscillated toraise and lowerthe head or abutment 2" by a fluidpressure cylinder 26" which has itsram 25 connected to arms 24 secured to the shafts 23. The horizontalmovement of the head or abutment to shift the ingot transversely of thetable is effected by uid pressure cylinders 10 having their rams 11connected to anarm 12 on the shaft 13, which frame of the manipulator. Ii

hold them steady, 1 posts 27 are arranged in sockets 28 formed 1;

fleeti's p 9 havingltheir outer E'Id Ii tiiected by links 14 to the'heador .llard the head 2 is secured to guidembers 4 mounted in suitablebearar ranged above the side frame of the able and on an auxiliary frame8.

uiding members are connected to opturn donnected to the rams 33 of fluidpressure 'cyhnders 34:

skilled in the art a shifting be. effected by moving the head 2horizontally over the feed rollers. While a turning of the ingot can beeffected by lowering the head until the shoulder 16* is below the ingotand then raising the head. A shiftmg and turning of the ingot can beeffected at the same time by moving the head horizontally andvertically.

I claim herein as my invention:

1. A manipulator for ingots having in combination ingot-carrying means,a head movable transversely of and abovethe ingotcarrying means,ingot-engaging portlons .movable with the head, supporting membersmovable above the ingot-carrying means and carrying the ingot-engagingportions, and means for moving the supporting members vertically andmeans for moving such members with respect to the vertically movingmeans.

of the ingot can 2. A manipulator having in combination means forfeeding an ingot, supporting members mov'ably/ supported above the lineof feed of the ingot at points laterally outside of the feeding means,ingot-engaging ortions carried by said members and means for shiftingthe supporting members vertically and horizontally.

3. A manipulator having in combination means for feeding an ingot,supporting members supported above the feeding means and movable in adirection at "an angle to said line of feed, a head carried by thesupporting members, means for shifting the head transversely to saidfeed and ingotturning means movable with and relative to the head.

4. A manipulator having in combination an ingot feeding means,supporting memmembers slidably mounted in said sleeves, ingot-movingmeans depending from the supporting memends of a cross-head 32 which isin bers movable above and in planes at or ap-- as or abutment 2 forshifting the '70 As will be readily understood by those sleeves andmeans for shifting the ingotmoving means.

6. A manipulator having in combination longitudinally movable supportingmembers, ingot-moving means depending from the supporting\members', astationary motor for moving the supporting means, andconnections'between the motor and the supporting members, saidconnections including means for slidably supporting said members.

7. A mnnipulator having in combination ingotfeeding means,'movablesupporting members, means arranged above the line of feed to support,said members, ingot moving means carried by the supporting members,

and means for shifting the su porting mem bers vertically and horizonta1y. V

8. A manipulator having; in combination ingot feeding meanslongitudinally movable supporting members arranged above the line ofmovement of the article being rolled, ingot-moving means depending fromthe sup porting members, and stationary motors for shifting thesupporting members vertically and horizontally.

In testimony whereof, I have hereunto set my hand. i JOSEPH FAWELL,
